I use a KVM switch that eats my EDID information from my monitor to my Nvidia GTX275 videocard. Therefore I have had to use a custom edid.bin file that I invoke in xorg.conf. So far that has worked very fine.
My GTX275 has to DVI outputs. So far I have used the port to the right (the one longest away from my motherboard). I would now like to use the other port (I have a MacOS snow leopard dual-boot install and in Mac OS you have to use the port closets to the motherboard to play games - strangely enough).
Now my problem starts.
When I change ports my LCD loses its signal half way trough boot and I have to change back to the other port to get a signal.
I have tried to create a new edid.bin file on the other port (bypassing the KVM) but so with the same result.
My xorg is as follows:

Do I have to make changes in the Device section? For instance changing DFP-0 to DFP-1 or something like that? I tried to do it but with no succes.
